The Model SD4-SS contains a piezoelectric horn which generates the
ANSI S3.41 temporal pattern in an alarm condition. During an alarm
condition, pressing the detector’s test switch will silence the piezo-

automatically maintains the sensitivity of the detector. The mounting
base installation is simplifi ed by the incorporation of features compat-
